Cup structure for bras

ABSTRACT

A bra includes two cups connected by a cup frame and each cup comprises an inner layer and an outer layer, and a flexible layer sandwiched between the inner layer and the outer layer. The flexible layer is made of fibers which are continuously woven with each other so as to be a high density and air-permeable flexible layer. The flexible layer maintains the shape of the cup and effectively prevents the cup from deformed permanently.

FIELD OF THE INVENTION

The present invention relates to a cup structure including a flexible layer sandwiched between an inner layer and an outer layer. The flexible layer is composed of fibers which are continuous woven.

BACKGROUND OF THE INVENTION

A conventional cup structure of a bra is disclosed in FIG. 10, and generally includes an inner layer 40 and an outer layer 400, and a fine cotton layer 41 is sandwiched between the inner layer 40 and the outer layer 400. The inner layer 40 and the outer layer 400 are made by cotton and woven in one direction so that the cup can only be extended in the direction. If the cup is applied a force in a direction other than the weaving direction, the cup tends to be deformed permanently. Furthermore, the fine cotton layer 41 is not strong enough to support the whole cup so that the cup cannot maintain its shape after a period of use and wash. This is one of the reasons that the bars have to be replaced so frequently.

The present invention intends to provide a cup structure for a bra wherein the cup includes a flexible layer sandwiched between an inner layer and an outer layer and the flexible layer is durable and not deformed permanently.

SUMMARY OF THE INVENTION

The present invention relates to a cup structure which comprises an inner layer and an outer layer, and a flexible layer sandwiched between the inner layer and the outer layer. The flexible layer is made of fibers which are continuously woven with each other so as to be a high density and air-permeable flexible layer.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows the three layers of the cup of the present invention;

FIG. 2 is a cross sectional view to show the three layers of the cup of the present invention;

FIG. 3 shows a bra with two cups of the present invention and a lace fabric is connected to each cup;

FIG. 3-1 shows a cross sectional view of each cup in FIG. 3;

FIGS. 4 to 6 show the flexible layer can be stretched in different directions;

FIGS. 6 and 7 show that the flexible layer can be compressed;

FIGS. 8 and 9 show two different ways of weaving of the flexible layer, and FIG. 10 shows a conventional cup structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the cup structure of the present invention of a bra that includes two cups connected by a cup frame and each cup comprises an inner layer 10 and an outer layer 20, and a flexible layer 30 sandwiched between the inner layer 10 and the outer layer 20. The inner layer 10 and the outer layer 20 are made by cotton or other soft material which his air permeable. The flexible layer 30 is made of fibers which are continuously woven with each other so as to be a high density and air-permeable flexible layer 30. As show in FIGS. 3 and 3-1, a lace fabric “a” can be connected to the outer layer 20 of each cup so as to have a good visual attraction.

FIGS. 4 and 5 show that the flexible layer 30 does not deform permanently even it is stretched in different directions and compressed as shown in FIGS. 6 and 7. By this important feature, the flexible layer 30 elongates the lift of the bra.

FIGS. 8 and 9 show that the flexible layer 30 can be made by different ways of weaving to have different thickness and density. The flexible layer 30 can b made by 100 percent of Nylon fibers, or by Tetolon fibers, Nylon fibers and OP fibers. A thickness of the flexible layer 30 is at least 2 mm so as to perform a better structural strength and effectively maintains the shape of the cup.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
